Hey guys,
After trying the led bulb route and failing I just installed a set of these http://www.ebay.com/itm/252058599477?_trksid=p2060353.m2748.l2649&ssPageName=STRK%3AMEBIDX%3AITAs I was installing them I tried them out and had no errors. Next day I start the car and get the above message. So turned it off and restart it and no messages. Been driving the car for almost a week now without any messages and today as soon as I start the car I get the same message again. Turned it off and start it again and it's gone. Now the question is, why do I have an intermittent here ?? If the computer is not seeing it, it should give me that message every each time upon starting the car. Am I missing something ??

Have you looked at my LED thread?

You mean the one about your e-bay bulbs ??

Benzman33

No, I don't do bay LED's...

That's the only thread I could find. Can you post a link on what you are talking about ??

Haven't had the chance to buy the new ones yet. I am thinking just replacing both headlights fully to go over to Xenons.

I cant drive it at night. Compared to my Audi its like I have no lights. The Audi has Xenons with Xenon match fog lights so I can see for miles.

Regardless of where the LED bulbs are installed, their current draw is not sufficient enough to allow the 'burned out bulb' circuitry to detect it as operational. MB electrical engineers assume each bulb location will draw X-amount of current. Anything less, i.e.: LED bulbs, and the circuit 'sees' it as a burned out situation. It's the nature of the design.

What ^ said. That's why you need canbus LEDs which draw same amount of current as halogen. We have such plug and play bulbs.

Jeff thank you,
I agree with everything you said but the part I do not understand is why will the error be intermittent ?? The x-amount each bulb draws will be the same in every start up and it should be detected as not operational each time vs once a week that my problem occurs....Is that right ??

AZN,
I went the canbus LED before but the bulb would not stay in place and every time I would put the cover on to screw it, it would move changing the direction of the led's. Hence I went with the whole Light Housing instead. Do you guys sell the whole light housing like the one I purchased of e-bay ?? If you do, I will buy it right now

MB-Dude

I suspect the LEDs you installed are on the cusp of drawing enough current sometimes, then sometimes not. The variable is the battery/charging circuit and overall current draw while the car is operating. Although we like to think that any car is a steady 12vDC machine, in reality it's somewhat variable. Less voltage = less current flow through the LEDs. One test might be to start the car when the battery is known to be fully charged, then turn everything electrical off except for the lights. If the bulb-burnt out circuit does not activate, then begin turning on the radio, AC, move the seats, etc. If you are electronically-inclined, you could add a bypass resistor to allow just a small amount of additional current flow.
Cheers,
Jeff

Sorry, we don't sell the housing. The canbus bulbs that shifted were from us using our design?

If you want to get your housing replacement issue to work though, would have to probably splice in resistors.

Thanks guys, I was worried that it would come down to resistors

Jeff,
I believe you stand correct
I have been watching this closely and I realized that if the car sits for a day or two and I go to start it, that first start the error comes on. But every start after that it doesn't. So if I drove it every day with no sitting for long periods of time the error will not come back. In few words when the voltage is lower, that's when the error occurs but if the voltage is higher it don't. I am sure that with the help of couple resistors I can make it work but I am not going that route. Gonna keep it like this for now and if the error get's to me, I will go back to the oem. Thanks everyone !!

I installed LED licence plate lights a while, and normally I don't get any error messages.

However, if I turn the lights on BEFORE I turn the ignition on, I get two bulb fail error messages.

Try that.

Thanks Nick, I will give it a shot. If not, I been thinking of going back to the OEM and getting a set of bulbs from AZN above...

The error codes come up on the dash only when the automatic sensors are activated (at night or when its dark) they shouldnt come up during the day unless you manually turn the lights on. I know because I am having the same exact issue. You have to buy LED bulbs with a loaded resistor in them for it to work. That will draw the same power as the regular bulb tricking the MB system. Hope this helps

Thanks bud. I did try the bulbs before changing the housing but did not like them since they were moving all over the place when I went to put the lens back on in order to screw it
